V I i q A v a a #9 l I a I I /e I I I MZIMSS:

citizen of the U ot l-la rrisonvllle, county of dass, and State of Mlssouri, have invented {1 will smvss Misti Apnlicazion filed Bohemian 5, 1915*.

certain new end useful lmprovsmei'it in Devices Checking the Booking. and Rcbounding of ivohiclcs, of which the following is u C03Q1- jolete specification.

The present invention pertains to vehicle. spring devices and'eims to provide animprovcd auxiliary spring mechanism, the operation of which will tend to reduce or check" the rockin as well as the i eboundin movement of the vehicle to which the improved mechanism is applied. e

In carrying out the invention, provide auxiliary spring devices adapted to be asso ciated in connection with opposite sides or the vehicle body adjacent the opposite ends of the transverse supporting spring, and so arranged as not only to check any rocking tendency of the vehicle in either direction but also to prevent any undue rebounding movement thereof.

It is also sought to provide a device of the character described which will add n1aterially to the riding comfort of the vehicle, While incidentally reinforcing tho action of the main rear vehicle springs and also 1% ducing the danger of thevchicle over-turn ing on account of excessive rocking movomont.

If is also sought to devise sslmplc, inexpensive and durable device of this character which will require no alteration in the ve hiele to wliicli the some isto be applied.

lWith these general objccts in view the in" vention will now be described by reference to the accompanying drawing illustrating one form of construction which I have do vised for emlimiying the improvement, after which the novel features will be defined in. the ascended claims:

In tie drawing Figure 1 is e rear end view, showing a portion of vehicle lmvin applied thereto a set of spring devices on: flying the present improvement;

Fl 2 is o transverse taken on the line 2 5: of Fig. 1;

is an enlarged detailed view oftlio auxiliary spring; and

ig. 5 is a perspective view showing one elements. Referring now to the drawing in detail, this illustrates the improved mechanism as applied to the rear end'of a vehicle comprising the rear axle housing 6, to which is connected in the usual manner tn main rear supporting spring 011 this transverse spring 7, is suitably mounted. a channel member 8, whereby the spring '7 is connected to the vehicle body 9, the latter being sccureo to said channel member by means of a series of bolts 10.

Within each of tho ends of said channel member is rigidly scoured tiller 11, having a, suitable bolt opening 12, whereby the some v means of one of tic b lts 1e), of said bars 11, being secured in place with its inner end abutting against the next adjacent bolt 10. Each of the bars 11 also projects outwardly away from the end of the channel member 8, and laterally 9, Where the free end of cum bar is provided, with a hook portion 13, adapted. for supporting engagement with the upper loop end 34, of :1 coil tension spring element T e lower end of the spring 15 is provided a loop 16, extending at right angles to the loop i l, and adapted for supporting engagement with a strzip 1?. .Tliis strap 1? is of a suitable length adapted to span the distance between the lower end of the spring and the axle 6, extonding around the axle and astride the transverse supporting spring 7.

For the purpose of spreading the strap 17, and preventing the some from wearing on- 'cinent with the spring: 7, V-slmpcd stirprovidcd, this stirrup mounted within loop 16, and embracing the strap 17., opposite sides of said loop. The end portions of me stirrup 18 are formed with suitable lugs l3, adapted to engage the side edges of strap and retaining the some in proper position on said stirrup. The strap 17 is firovidcd with a suitable buckle 20 whereby any slack in each of the spring devices may lie when appli d to the witl thc Rommel upright position. l I

. lit will thus lac apparent that l have pr body 9 in initially taken up vided a simple, durable and eflicient device for carrying out the desired objects of the invention, and one which requires no cutting or punching in order to apply the same in its operative position, the device simply requiring the loosening of a pair of bolts 10, to secure the same in place with the strap 17, embracing the adjacent end of the axle 6, and extending on opposite sides of each end of the transverse spring 7. It will be readily understood that any undue rebounding of the vehicle will he promptly checked, and at the same time any excessive rocking move.-

' tains the same entirely out of engagement with the transverse spring at all times. The device is entirely free from complications and may he easily and quickly attached in position by any unskilled person. ()bviously, the use of the device also adds greatly 'to the ease and riding comfort of the car,

and while the device is particularly suitable and desirable in connection with small sedans and touring cars, it is apparent that the same would be equally desirable and efiicient if applied in the same manner to small delivery vehicles, such as laundry, bread and e grocery trucks.

While I have illustrated what I re ard as the preferred form of construction, desire to reserve the right to make such changes as may fairly fall within the scope of the appended claims.

What I claim is: l

1. The combination with a vehicle body, axle and transverse -supporting spring, of a bar secured rigidly to said body and projecting laterally therefrom, a coil tension spring carried by the uter end of said bar, a strap looped arou d said axle and connected tautly with the lower end of said coil spring, and a spreader device associated with said strap and coil spring for maintaining said strap out of engagement with said transverse spring.

2, The comhination with a vehicle body,

axle and transverse supporting spring, of a bar secured rigidly to saidbody and projecti-ng laterally therefrom, a coil tension spring carried by the outer end of said bar,

a strap looped around said axle and .connected tautly to the lower end of said coil spring, and a stirrup carried by said lower end of the coil spring in engagement with said strap and acting to maintain the latter out of engagement with said transverse spring. 7

In witness whereof, I hereto 'affix my 81g:- nature.
